wondering if any1 has does extensive engine work to there yz400/426
Hotcams IN/EX Cams
Polished ports and combustion chamber
High compression piston
Hotrods crankshaft and rod
Wiseco clutch basket
40mm Keihin carb off 08yz450, bored
FMF exhaust system
looking at geting a programmable MSD CDI and Dynotuned
All work performed by me
Runs a compression ratio of 14.5 : 1
Runs on E85 race fuel (wheat blend, not the cheap stuff u get on pump)
runs great, no probs with the E85 and seals, no corrosion. its alcohol, it keeps everythig clean.
there are alot of myths about the E85 fuel and bikes. i have stored half a tank in by bike for 2 months and it ran fine, carb was still spotless.
only alcohol based Fuels will handle a 14.5:1 compression ratio, it auto-ignites nearly 100 celcius higher than gasoline.
i used to own a 2008 KTM 530 EXC-F and this yz400 just puts the 530 to shame.
its the most powerful dirt bike ive ever rode (ive owned ALOT)
want to know if any1 else has something as worked
